Nitrogen dioxide decomposes at 300 °C via a second-order process to produce nitrogen monoxide and oxygen according to the following chemical equation:

2 NO2(g) → 2 NO(g) + O2(g).

A sample of NO2(g) is initially placed in a 2.50 L reaction vessel at 300 °C. If the half-life and the rate constant at 300 °C are 11 seconds and 0.54 L mol-1 s-1, respectively, how many moles of NO2 were in the original sample?
◦ 0.17 mol
◦ 0.42 mol
◦ 5.9 mol
◦ 15 mol
